Not able to install any software from software center

[adapaganesh]

Since few weeks, i'm not able to install any software from software center.
The error message was "Please check your internet connection". Internet connection is fine, i'm able to browse it and also i am able to download the updates from the Ubuntu.
My attempts to fix this issue:
1. I tried changing the mirror location from India to other(Bangladesh, geographically near to India).
2. Then run "sudo apt-get update"
3. Tried installing software from software center.

This time, i did not get the install button but "Use This Source" button. So, i reverted to India mirror and now reporting this issue to you.

I sincerely need a helping hand to overpower this issue so that i can enjoy my love with Ubuntu.
